I had a tool that I used with VB that had a list of Win API Constants, Types (Stucts) and Function Declarations that I could copy and paste into my VB procedures. Is there such a thing in Real Basic? Also, where can I get more information on declaring external functions?

Thanks to both of you for the quick replies. I really appreciate it. I use, or should I say used, many external functions in my VB code. I'm glad to see that they are supported. I read the section on Declares the other night. It gets rather involved when you are dealing with multiple operating systems!
